Exchange greylisting and I can’t send email to these domains

I was getting calls from one account running Exchange 2003 that at random times that they could not send email to one domain. I looked at logs and I see nothing helpful. My account found ways around the issue, maybe faxing or alternate email accounts. One day I found this article by Michael which solved that account’s problem. At least I have not heard anyone complain in a while. The deadly greylisting where the mail server does not answer a sending email server’s command immediately. The idea is to prevent spammers from doing their evil. http://theessentialexchange.com/blogs/michael/archive/2007/11/16/exchange-2003-sp2-and-greylisting.aspx glitchretry is what I modified. http://technet.microsoft.com/en-us/library/aa998772(EXCHG.65).aspx I … Continue reading Exchange greylisting and I can’t send email to these domains

Network print sharing devices not working, uncheck SNMP.

Application server was replaced. We had an OKI B4600 and a Dymo Labelwriter 400 attached to cheap print sharing devices. They worked fine for years. They did not work after new server. I goofed around for a lot of hours one day and Quest support was no help. They supplied the printers but not the print sharing devices. Dymo worked fine when attached to server directly via USB cable but not through usb print server. I did not try to carry the OKI ovver but it printed fine from laptop directly attached to usb cable. It happened to be a … Continue reading Network print sharing devices not working, uncheck SNMP.

HP printer with no screen to change ip and wizard does not let you change ip

I got a call about a HP LJ2035n. The user could not see the printer using the wizard. Is the network connection on the printer lit up? No. Read the wall jack and go plug it in on the switch. Drama comments so I go to visit. Actually that is not a bad thing as the cabling infrastructure is a mess due to a remodeling project a few years ago that was done out of sequence. I get the printer plugged in and the wizard sees the printer but cannot administer it. Power cycle the printer does not help. That … Continue reading HP printer with no screen to change ip and wizard does not let you change ip

Citrix ICA cache corrupt?

I don’t remember if I told this story. An account I have works on the hospital portal. They click on something and a Citrix session starts up. Click deep enough and it pops up an extranet Internet Explorer session that is supposed to set up some proxy settings. I beat my head against the wall trying to get it to work. The hospital spent time trying to fix it. I finally compose a long note to my friends to see if they had any ideas. 3 long paragraphs later I tried to do a summary flow chart. Once I did … Continue reading Citrix ICA cache corrupt?

Intel DG33 sort of dead nic

I got a call about a workstation with a dead nic. In device manager it shows up with an exclamation mark.  Vista 64 bit box. I tried to install the drivers from the Intel CD which did not help. I tried the drivers from the Intel web site which did not help. An Intel salesman calls me while I am doing this. I fuss that I am working on a DG33. He says what is that. A salesman that does not know his products. That motherboard has not been deprecated that long ago. In any event he got me a … Continue reading Intel DG33 sort of dead nic

Exchange 2003 messages stuck in local delivery queue for one user

I delivered a new SBS 2003 to replace an old SBS 2003. We had some goofed up Active Directory stuff so the thought was we would just start from scratch but pick up the old Exchange database and place it on the new server. That worked fine but we had some issues with speed of backup.  The lab backup and remount worked fine but it took many hours to copy the Exchange database. Anyway there was a bit of overlap that for some reason I did an Exmerge from old server to catch 2 days of email. I really do … Continue reading Exchange 2003 messages stuck in local delivery queue for one user

My SBS backups are failing. Media messages.

I can’t backup.Something about media  or it starts a backup and bombs along the way. I start with the basics. We currently use usb drives to back up for the most part. Can you see the usb drive from My Computer? Yes is good. No means you need to power down the usb drive, check the connections on the usb cable and power it back up. If it still does not appear try plugging it in to your laptop. Yes you see it. How much free space does it have? How many backups is the server supposed to save to … Continue reading My SBS backups are failing. Media messages.

I can’t print. Tales of tcpip printing with some RDP fun.

I can’t print. Tales of tcpip printing. I have recently had calls about I cannot print. The first was a peer to peer I cannot print. I visit and I cannot ping the printer based on the printer tcpip port properties. Is the printer plugged in to the network? Yes for one and no for another.  What is the ip? How is the printer getting its ip? What is doing dhcp? So the first account had a router serving up ips starting at 1. They had about 10 workstations. Printer was hanging out at .5 with a static ip. Ip … Continue reading I can’t print. Tales of tcpip printing with some RDP fun.

Stuck network switch ports and workstation drivers

I got a call that two workstations at check in were off the network. I suggested running Malwarebytes Antimalware. That has fixed a few machines at that account. Note that I just got this account. It has almost 100 devices at two locations, no domain, no centralized anti-virus console, no dhcp, four servers, a Sonicwall, A Cisco Pix, no network documentation. And they are about 1.5 hours from the house in good traffic. Wah. So the local guy ran the anti-malware program which came out clean. He changed out the workgroup switch which did not help.  They were attached to … Continue reading Stuck network switch ports and workstation drivers
